RELATED APPLICATION

The present disclosure claims priority to U.S. Provisional Patent Application No. 63/063,481, filed Aug. 10, 2020, the entire content of which is herein incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to inhalation devices. More particularly, the present disclosure relates to smoking pipes and related kits and methods.

BACKGROUND

Smoking pipes typically comprise a bowl, a pipe stem, and a mouthpiece at the end of the pipe stem. The bowl may hold an amount of smokable material, such as tobacco, that may be lit by fire to generate smoke. The pipe user may inhale on the mouthpiece to draw the smoke from the bowl through the pipe stem and into the mouth and lungs of the pipe user.

Conventional smoking pipes often have stems made of acrylic, silicon rubber, or hard rubber (also known as vulcanite or ebonite). Acrylic stems can be fragile and may be susceptible to cracking or breaking if the pipe is dropped. Hard rubber stems are less fragile but are subject to oxidation. As a result, pipe stems may need to be replaced and the old stems may be discarded as waste. In addition, acrylic and silicon or hard rubber do little to absorb heat or volatile chemicals from the smoke as it passes from the bowl to the mouthpiece.

In some embodiments, the tubular body comprises a plant stem, such as a stem from a Cannabis plant.

As used herein the terms “a,” “an,” and “the” may include plural referents unless the context clearly dictates otherwise.

It is to be understood that directional or relative terms such as “upwards”, “backwards”, “vertical”, “horizontal”, “upper”, “lower”, “side”, “top”, “bottom” and the like are used for ease of description and illustrative purposes, and embodiments are not limited to a particular orientation of the smoking apparatuses described herein during use or normal operation.

As used herein, the term “smoking apparatus” refers to any apparatus configured to burn or combust a smokable material to generate smoke for inhalation by a user. In some embodiments, the smokable material comprises a plant material. Non-limiting examples of suitable plant materials include dried tobacco, dried Cannabis, and dried herbs.

An example smoking apparatus 100 will be described with reference to FIGS. 1, 2A and 2B. The smoking apparatus 100 in this embodiment comprises a first end member 102, a second end member 104, and a tubular body 106 therebetween.

In some embodiments, the tubular body 106 comprises an organic material. In some embodiments, tubular body 106 comprises a plant part. In some embodiments, the plant part comprises a plant stem. As used herein, a plant “stem” or “stalk” refers to a primary plant axis that supports other plant parts such as leaves, flowers, and/or fruits. The tubular body 106 may comprise the entire plant stem or any portion thereof having a desired length. In some embodiments, the plant stem has been dried by any suitable drying means and cut to the desired length. In some embodiments, the cut ends of the stem have been prepared by any suitable means to prevent fibres from coming loose.

In some embodiments, the plant stem is from a Cannabis plant. As used herein, “Cannabis plant” refers to a plant of the Cannabis genus. In some embodiments, the Cannabis plant is Cannabis sativa L. In some embodiments, the Cannabis plant is a variety or cultivar of industrial hemp. As used herein, “hemp” or industrial hemp” refers to a variety or cultivar of Cannabis that is grown for production of fiber and/or seeds rather than for medicinal and/or recreational applications. A plant from a hemp variety or cultivar may contain less than about 0.3% THC or less than about 0.2% THC (Δ⁹-tetrahydrocannabinol) by dry weight of its leaves and flowers. In other embodiments, the Cannabis plant is a drug-type Cannabis variety or cultivar. As used herein, “drug-type” refers to a variety or cultivar of Cannabis that is grown for use in medicinal and/or recreational applications. A plant from a drug-type Cannabis variety or cultivar may contain greater than about 0.3% THC by dry weight of its leaves and flowers.

In some embodiments, the plant stem may be from a hemp variety or cultivar displaying a hollow core trait. As used herein, a “hollow core trait” refers to a characteristic of a plant in which the plant stem has a relatively hollow core along its longitudinal axis, although the diameter of the hollow core may vary along the length of the stem. Non-limiting examples of suitable cultivars include the “Silesia” or CSFX-2 hemp cultivars, which produce stems with relatively hollow cores. In other embodiments, the plant stem may be from any other suitable variety or cultivar of Cannabis that demonstrates a relatively hollow core.

In other embodiments, the plant stem is from any other suitable type of plant. In other embodiments, the tubular body 106 is made of any other suitable material.

As shown in FIG. 3, the tubular body 106 has a first end 105 and a second end 107. The tubular body 106 may define a longitudinal conduit 109 therethrough extending from the first end 105 to the second end 107. In this embodiment, the tubular body 106 is approximately straight (i.e. linear) and extends along a longitudinal axis 101 (the longitudinal axis 101 is visible in FIG. 1). In other embodiments, the tubular body 106 is curved. In some embodiments, the tubular body 106 has a natural curvature depending on the particular portion of the plant stem used to form the tubular body 106. The tubular body 106 may be any suitable length and diameter. In some embodiments, the tubular body 106 has an outer diameter D1 of between about 0.5 and about 1.5 inches. In some embodiments, the tubular body 106 may be non-uniform in diameter such that the diameter D1 varies along the length of the tubular body 106. The non-uniformity may be due to natural variations in the plant stem forming the tubular body 106.

The first end member 102 may engage the first end 105 of the tubular body 106 and the second end member 104 may engage the second end 107 of the tubular body 106 (the first and second ends 105 and 107 are visible in FIG. 3). In some embodiments, the first and second end member 102 and 104 sealingly engage the first and second ends 105 and 107 of the tubular body 106. As used herein, “sealingly engage” refers to engaging in such a way as to substantially prevent airflow therebetween, although the seal may not be perfectly airtight. In some embodiments, the tubular body 106 is longitudinally reversible such that the second end member 104 can sealingly engage the first end 105 and the first end member 102 can sealingly engage the second end 107.

Referring again to FIGS. 1 to 2B, the first end member 102 may comprise a mouthpiece portion 108 and a first sealing portion 110. The mouthpiece portion 108 may be any suitable shape to be held between a user's lips. The mouthpiece portion 108 may comprise a suction opening 132 (shown in FIG. 5B and discussed below). When the first end member 102 is sealingly engaged with the tubular body 106, the suction opening 132 may be in fluid communication with the longitudinal conduit 109 of the tubular body 106.

The first sealing portion 110 may receive the first end 105 of the tubular body 106 therein. In some embodiments, the first sealing portion 110 may receive a first section 111 of the tubular body 106 therein (the first section 111 is visible in FIG. 3). In some embodiments, the first section 111 of the tubular body 106 is between about 0.5 and about 2 inches in length. In this embodiment, the first section 111 is between about 1.0 and about 1.5 inches in length.

In some embodiments, the first sealing portion 110 snugly receives the first section 111 of the tubular body 106 such that the first sealing portion 110 and the tubular body 106 are in sealing engagement. In other embodiments, the first sealing portion 110 has a clearance fit with the tubular body 106. In these embodiments, an adhesive/sealing compound may be applied between the tubular body 106 and the first sealing portion 110 to facilitate sealing engagement. The adhesive may comprise a silicone or an epoxy, such as a bio-based epoxy, or any other suitable type of adhesive. As discussed in more detail below, in other embodiments, a sealing element such as an O-ring (not shown) can be provided between the tubular body 106 and the first sealing portion 110 to facilitate sealing engagement.

The second end member 104 may comprise a receptacle 112, a choke element 114, a second sealing portion 116, and an adjustment ring 120. The receptacle 112 in this embodiment is approximately cylindrical in shape. In other embodiments, the receptacle 112 may be any other suitable shape. The receptacle 112 may define an open chamber 126 therein to receive a smokable material (not shown) for smoking. In some embodiments, the chamber 126 is approximately cylindrical or frustoconical in shape. In other embodiments, the chamber 126 may be any other suitable shape.

The receptacle 112 may comprise an upper opening 128 and a lower opening 130 (the lower opening 130 is visible in FIG. 2A) to the chamber 126. The upper opening 128 may allow the smokable material to be added to the chamber 126 and lit to generate smoke. For example, a user may light the smokable material by contacting the material with a flame from a lighter or a match via the upper opening 128. The lower opening 130 may connect the chamber 126 to the choke element 114 therebelow.

The choke element 114 may interconnect the receptacle 112 with the second sealing portion 116. The choke element 114 may thereby fluidly connect the chamber 126 with the longitudinal conduit 109 of the tubular body 106. The choke element 114 may comprise an airflow opening 124, also referred to as a “choke” or “carb” hole, to allow fresh air to enter the choke element 114 and flow along the longitudinal conduit 109 as described below.

The second sealing portion 116 may receive the second end 107 of the tubular body 106 therein. In some embodiments, the second sealing portion 116 receives a second section 113 of the tubular body 106 therein (the second section 113 is visible in FIG. 3). In some embodiments, the second section 113 of the tubular body 106 is between about 0.5 and about 2 inches in length. In this embodiment, the first section 111 is between about 1.0 and about 1.5 inches in length.

In some embodiments, the second sealing portion 116 snugly receives the second section 113 of the tubular body 106 such that the second sealing portion 116 and the tubular body 106 are in sealing engagement. In other embodiments, the second sealing portion 116 has a clearance fit with the tubular body 106. In these embodiments, an adhesive may be applied between the tubular body 106 and the second sealing portion 116 to facilitate sealing engagement, as discussed above with respect to the first sealing portion 110. As discussed in more detail below, in other embodiments, a sealing element such as an O-ring (not shown) can be provided between the tubular body 106 and the second sealing portion 116 to facilitate sealing engagement.

In this embodiment, the second sealing portion 116 further comprises an annular collar 122. The annular collar 122 may be configured to be gripped by the user's fingers to hold the second end member 104. For example, the user may grip the annular collar 122 to hold the smoking apparatus 100 steady during a smoking session or to facilitate engaging/disengaging the second end member 104 and the tubular body 106.

The adjustment ring 120 may be disposed between the second sealing portion 116 and the choke element 114. In some embodiments, the adjustment ring 120 is threadingly engaged with the choke element 114 as discussed in more detail below.

The adjustment ring 120 may allow the choke element 114, and thus the receptacle 112, to be secured in a desired position. As discussed above, when the tubular body 106 is derived from a plant stem, it may have a natural curvature. As such, a user may wish to rotate the smoking apparatus 100 such that the tubular body 106 is in a suitable position for the user to comfortably hold during use. When the smoking apparatus 100 is rotated, the receptacle 112 may be in a position in which the upper opening 128 faces downwards or to the side rather than upwards as desired. The choke element 114 may thereby be rotated with respect to the second sealing portion 116 into the desired position such that the upper opening 128 of the receptacle 112 faces upwards. The adjustment ring 120 may then be rotatably adjusted (i.e. tightened) to secure the choke element 114 in the desired position.

In use, the user may add smokable material to the chamber 126 and light it to generate smoke. The user may then place their mouth over the mouthpiece portion 108 and inhale through the suction opening 132 to draw smoke from the chamber 126, through the choke element 114 and the longitudinal conduit 109, and into the user's mouth and lungs for consumption. The user may place a thumb or finger over the airflow opening 124 of the choke element 114 as they start to inhale smoke from the material in the chamber 126 and then release their thumb or finger to allow air to enter the choke element 114 and push any remaining smoke through the longitudinal conduit 109 and into the user's mouth and lungs.

Therefore, in this embodiment, the tubular body 106 functions to convey the smoke from the second end member 104 to the first end member 102. By using a portion of a plant stem to form the tubular body 106, the tubular body 106 may at least partially absorb heat and/or volatile chemicals from the smoke as it passes through the longitudinal conduit 109 and may thereby function to cool and/or filter the smoke. The tubular body 106 may also be durable and environmentally friendly.

In some embodiments, the receptacle 112 is removable from the choke element 114 and replaceable with at least one other attachment (not shown). Non-limiting examples of suitable attachments include: a substitute receptacle of a different size or shape; a filtration device; and any other suitable attachment for a smoking apparatus. In some embodiments, the filtration device is configured to engage the receptacle 112 (or any other suitable receptacle) such that smoke from the chamber 126 of the receptacle 112 is filtered through the filtration device before it flows into the choke element 114.

The first and second end members 102 and 104 will now be discussed in more detail with reference to FIGS. 4 to 11B.

FIG. 4 is an exploded view of the first end member 102 showing the mouthpiece portion 108 and the first sealing portion 110.

The mouthpiece portion 108 is shown in FIGS. 5A and 5B. The mouthpiece portion 108 has a first end 115 and a second end 117. As shown in FIG. 5B, the first end 115 may define a first opening 132 (also referred to herein as the suction opening 132) and the second end 117 may define a second opening 134. In some embodiments, the suction opening 132 is approximately circular or oval in shape. In other embodiments, the suction opening 132 is any other suitable shape. The mouthpiece portion 108 may further comprise an internal conduit 136 extending from the suction opening 132 to the second opening 134.

The mouthpiece portion 108 may be configured to releasably engage the first sealing portion 110. In this embodiment, the mouthpiece portion 108 comprises a threaded projection 138 at its second end 117 for engaging the first sealing portion 110. The internal conduit 136 may extend through the threaded projection 138 to the second opening 134.

The first sealing portion 110 is shown in FIGS. 6A and 6B. The first sealing portion 110 has a first end 119 and a second end 121. As shown in FIG. 6B, the first end 119 may define a first opening 140 and the second end 121 may define a second opening 142. The first opening 140 may be configured to receive the threaded projection 138 of the mouthpiece portion 108. A threaded recess 144 may be provided proximate the first opening 140 to threadingly engage the threaded projection 138. Therefore, in this embodiment, the threaded projection 138 can be threaded and unthreaded from the threaded recess 144 to engage and disengage the mouthpiece portion 108 and the first sealing portion 110. In other embodiments, the mouthpiece portion 108 and the first sealing portion 110 are releasably engaged by any other suitable means and embodiments are not limited to the threaded coupling mechanisms described herein.

The second opening 142 may be configured to receive the first end 105 of the tubular body 106 therethrough. A channel 146 may extend from the second opening 142 to the threaded recess 144. The channel 146 may be configured to receive the first section 111 of the tubular body 106 therein such that the first section 111 of the tubular body 106 is sealingly engaged with the first sealing portion 110. The channel 146 may have a longitudinal length L1 corresponding to the length of the first section 111 of the tubular body 106. In some embodiments, the length L1 is about 0.5 to about 2 inches. In this embodiment, the length L1 is about 1.0 to about 1.5 inches. In other embodiments, the length L1 is any other suitable length.

The second opening 142 and the channel 146 have an inner diameter D2. In some embodiments, the inner diameter D2 is approximately equal to the outer diameter D1 of the tubular body 106. In other embodiments, the inner diameter D2 may be slightly larger than the outer diameter D1 of the tubular body 106. In some embodiments, the diameter D2 is between about 0.5 to about 1.5 inches. In this embodiment, the diameter D2 is between about 0.9 and about 1.1 inches, or approximately 1 inch. In other embodiments, the diameter D2 is any other suitable diameter based on the diameter D1 of the tubular body 106.

As discussed above, in some embodiments, an adhesive may be applied between the first section 111 of the tubular body 106 and the inner wall of the channel 146 to facilitate sealing engagement

In other embodiments, the first sealing portion 110 may be adjustable to sealingly engage tubular bodies of varying outer diameters. For example, a sealing element of a desired size may be received into the channel 146 of the first sealing portion 110 to reduce the inner diameter D2 of the channel 146 accordingly. The sealing element may comprise an O-ring, a compression ring, or any other suitable type of sealing element. In these embodiments, the sealing element may sealingly engage the first section 111 of the tubular body 106 when the first section 111 is received into the channel 146.

Therefore, when the mouthpiece portion 108 is engaged with the first sealing portion 110, and the first sealing portion 110 sealingly engages the first end 105 of the tubular body 106, the suction opening 132 may be in fluid communication with the longitudinal conduit 109 of the tubular body 106 via the internal conduit 136.

In this embodiment, the mouthpiece portion 108 and the first sealing portion 110 are separate parts that are releasably coupled together. Therefore, in some embodiments, the first end member 102 may be relatively easily disassembled for cleaning and/or replacement of parts. In some embodiments, the mouthpiece portion 108 can be replaced with a different mouthpiece portion if desired. The different mouthpiece portion may be a different size, shape, and/or material as desired by the user.

In other embodiments, the mouthpiece portion 108 and the first sealing portion 110 may be permanently coupled or integral with one another and the first end member 102 may be a single, integrated part.

The mouthpiece portion 108 and the first sealing portion 110 may each be made of any suitable material. In some embodiments, the mouthpiece portion 108 and the first sealing portion 110 are made of the same material. In other embodiments, the mouthpiece portion 108 and the first sealing portion 110 are made of different materials. In some embodiments, at least one of the mouthpiece portion 108 and the first sealing portion 110 are made of metal. Non-limiting examples of suitable metals include brushed nickel, stainless steel, chrome, brass, or gold. However, embodiments are not limited to the specific materials recited herein and the mouthpiece portion 108 and the first sealing portion 110 may each be made of any suitable material.

FIG. 7 is an exploded view of the second end member 104 showing the receptacle 112, the choke element 114, the adjustment ring 120, and the second sealing portion 116.

The receptacle 112 is shown in FIGS. 8A and 8B. The receptacle 112 has an upper end 123 and a lower end 125. As described above, the receptacle 112 in this embodiment comprises the chamber 126 with the upper and lower openings 128 and 130 thereto. As shown in FIG. 8B, in some embodiments, the receptacle 112 may further comprise an internal conduit 148 extending from the lower opening 130 of the chamber 126 to the lower end 125 of the receptacle 112. The lower end 125 may define a lower opening 150 to the internal conduit 148. Alternatively, the internal conduit 148 may be omitted and the chamber 126 may extend all the way to the lower end 125 of the receptacle 112.

In some embodiments, the receptacle 112 further comprises a filter (such as the filter 227 shown in FIG. 12B as discussed below) within the chamber 126, extending across the lower opening 130. The filter may prevent fibres and/or residue of the smokable material in the chamber 126 from entering and clogging the choke element 114.

In some embodiments, the receptacle 112 is configured to releasably engage the choke element 114. In this embodiment, the receptacle 112 comprises a threaded projection 152 at its lower end 125 for releasably engaging the choke element 114. The internal conduit 148 may extend through the threaded projection 152 to the lower opening 150.

The choke element 114 is shown in FIGS. 9A to 9C. The choke element 114 has a first end 127 and a second end 131. As shown in FIG. 9C, the first end 127 may define a first opening 124 (also referred to herein as the airflow opening 124) and the second end 131 may define a second opening 154. An internal conduit 156 may extend longitudinally through the choke element 114 from the airflow opening 124 to the second opening 154.

The choke element 114 may further comprise an upper opening 158 to the internal conduit 156. The upper opening 158 may be configured to receive the threaded projection 152 of the receptacle 112 therein, thereby fluidly connecting the chamber 126 with the internal conduit 156 via the internal conduit 148 of the receptacle 112. The combination of the internal conduit 148 of the receptacle 112 and the internal conduit 156 of the choke element may thereby form a substantially continuous internal conduit through the second end member 104. In other embodiments, the internal conduit 148 of the receptacle 112 may be omitted and the chamber 126 may be in direct fluid communication with the internal conduit 156 of the choke element 114.

A threaded recess 160 may be provided proximate the upper opening 158 to threadingly engage at least a portion of the threaded projection 152. Therefore, in this embodiment, the threaded projection 152 can be threaded and unthreaded from the threaded recess 160 to engage and disengage the receptacle 112 and the choke element 114. Alternatively, the choke element 114 can comprise a threaded projection and the receptacle 112 can comprise a threaded recess, the threaded projection of the choke element 114 received into the threaded recess of the receptacle 112.

In other embodiments, the receptacle 112 and the choke element 114 are releasably engaged by any other suitable means and embodiments are not limited to the threaded coupling mechanisms described herein.

In some embodiments, the choke element 114 is configured to releasably engage at least one additional attachment (not shown) in place of the receptacle 112. As discussed above, the attachment may be a substitute receptacle, a filtration device, or any other suitable type of attachment. In some embodiments, the attachment comprises a threaded projection (similar to the threaded projection 152 of the receptacle 112) and the upper opening 158 and threaded recess 160 of the choke element 114 are configured to receive and threadingly engage the threaded projection. In other embodiments, the choke element 114 and the attachment are configured to releasably engage one another by any other suitable means and embodiments are not limited to threaded coupling mechanisms.

In some embodiments, where the attachment is the filtration device, the receptacle 112 is also configured to releasably engage the filtration device. When the receptacle 112 and the choke element 114 are engaged with the filtration device therebetween, the filtration device may be in fluid communication with both the chamber 126 of the receptacle 112 and the internal conduit 156 of the choke element 114. Thus, smoke from the smokable material may flow from the chamber 126, through the filtration device, to the internal conduit 156 of the choke element 114 and into the longitudinal conduit 109 of the tubular body 106.

The choke element 114 may interconnect the receptacle 112 with the second sealing portion 116. In some embodiments, the choke element 114 is configured to releasably engage the second sealing portion 116. In this embodiment, the choke element 114 comprises a threaded projection 162 at its second end 131 for releasably engaging the second sealing portion 116. The internal conduit 156 may extend through the threaded projection 162 to the second opening 154.

The second sealing portion 116 is shown in FIGS. 10A and 10B. The second sealing portion has a first end 133 and a second end 135. As shown in FIG. 10B, the first end 133 may define a first opening 164 and the second end 135 may define a second opening 166. The first opening 164 may be configured to receive the threaded projection 162 of the choke element 114 therein. A threaded recess 168 may be provided proximate the first opening 164 to threadingly engage at least a portion of the threaded projection 162. Therefore, in this embodiment, the threaded projection 162 can be threaded and unthreaded from the threaded recess 168 to engage and disengage the choke element 114 and the second sealing portion 116. Alternatively, the choke element 114 can comprise a threaded recess and the second sealing portion 116 can comprise a threaded projection, the threaded projection of the second sealing portion 116 received into the threaded recess of the choke element 114.

In other embodiments, the choke element 114 and the second sealing portion 116 may be releasably engaged by any other suitable means and embodiments are not limited to the threaded coupling mechanisms described herein.

The second opening 166 may be configured to receive the second end 107 of the tubular body 106 therethrough. A channel 170 may extend from the second opening 166 to the threaded recess 168. The channel 170 may be configured to receive the second section 113 of the tubular body 106 therein such that the second section 113 of the tubular body 106 is sealingly engaged with the second sealing portion 116. The channel 170 may have a length L2 corresponding to the length of the second section 113 of the tubular body 106. The length L2 may be the same or different than the length L1 of the first sealing portion 110. In some embodiments, the length L2 is between about 0.5 to about 2 inches. In this embodiment, the length L2 is about 1.0 to about 1.5 inches. In other embodiments, the length L2 is any other suitable length.

The channel 170 may has inner diameter D3. In some embodiments, the inner diameter D3 is approximately equal to the outer diameter D1 of the tubular body 106. In some embodiments, the diameter D3 is between about 0.5 to about 1.5 inches. In this embodiment, the diameter D3 is between about 0.9 and about 1.1 inches, or approximately 1 inch. In other embodiments, the diameter D3 is any other suitable diameter based on the diameter D1 of the tubular body 106.

Similar to the first sealing portion 110, if the inner diameter D3 is slightly larger than the outer diameter D1 of the tubular body 106, an adhesive may be used to facilitate sealing engagement between the tubular body 106 and the second sealing portion 116.

In other embodiments, the second sealing portion 116 may be adjustable to sealingly engage tubular bodies of varying outer diameters, as discussed above with respect to the first sealing portion 110. For example, a sealing element, such as an O-ring or a compression ring, may be received into the channel 170 to adjust the inner diameter D3 as desired.

Therefore, when the receptacle 112 is engaged with the choke element 114, the choke element 114 is engaged with the second sealing portion 116, and the second sealing portion 116 is sealingly engaged with the tubular body 106, the chamber 126 may be in fluid communication with the longitudinal conduit 109 of the tubular body 106 via the internal conduit 156 of the choke element 114.

The adjustment ring 120 is shown in FIGS. 11A and 11B. The adjustment ring 120 may be configured to receive the threaded projection 162 of the choke element 114 therethrough. The threaded projection 162 of the choke element 114 may therefore extend through the adjustment ring 120 and into the threaded recess 168 of the second sealing portion 116.

As shown in FIG. 11B, the adjustment ring 120 may comprise an inner threaded wall 172 to threadingly engage the threaded projection 162. The adjustment ring 120 may be rotated in a first direction to be moved along the threaded projection 162 away from the second sealing portion 116 and rotated in the opposite direction to be moved towards the second sealing portion 116. Moving the adjustment ring 120 away from the second sealing portion 116 may allow the choke element 114 to be rotated with respect to the second sealing portion 116 into a desired position. Moving the adjustment ring towards the second sealing portion 116 may secure the choke element 114 to the second sealing portion 116 (and thus the receptacle 112) in the desired position. In other embodiments, the directions may be reversed and moving the adjustment ring 120 towards the second sealing portion 116 secures the choke element 114 to the second sealing portion 116.

In this embodiment, the receptacle 112, the choke element 114, the adjustment ring 120, and the second sealing portion 116 are separate parts that are releasably coupled together. Thus, in some embodiments, the second end member 104 in is relatively easily disassembled for cleaning and/or replacement of parts. In some embodiments, the receptacle 112 can be removed and replaced with an alternative attachment, as discussed above. In some embodiments, the receptacle 112 is replaced with a receptacle of a different size, shape, and/or material if desired by the user. In other embodiments, the receptacle 112 is replaced with any other suitable attachment.

In other embodiments, two or more of the components of the second end member 104 may be permanently coupled or integral with one another. For example, the receptacle 112 may be permanently coupled or integral with the choke element 114; the choke element 114 may be permanently coupled or integral with the second sealing portion 116; and/or the second sealing portion 116 may be permanently coupled or integral with the adjustment ring 120. In other embodiments, the entire second end member 104 may be a single, integrated part. In embodiments in which the choke element 114 is permanently coupled or integral with the second sealing portion 116, the adjustment ring 120 may be omitted.

The receptacle 112, the choke element 114, the adjustment ring 120, and the second sealing portion 116 may each be made of any suitable material including, for example, any of the materials discussed above with respect to the first end member 102. In some embodiments, all of the components of the second end member 104 are made of the same material. In other embodiments, one or more components may be made of different materials. In some embodiments, components of different materials may be selected by a user to achieve a desired appearance.
